Am I right that what you have is this?
CREATE TABLE T (v integer);
INSERT INTO T (v) VALUES (1);
INSERT INTO T (v) VALUES (12);
INSERT INTO T (v) VALUES (3);
INSERT INTO T (v) VALUES (9);
INSERT INTO T (v) VALUES (4);
In that case you could do the following:
SELECT v FROM T ORDER BY v DESC LIMIT 3;
This will select the values, sort them in descending order and limit the
result to 3 rows.
I hope it helps.
